Recently installed new modem, etc., and though everything is up and running, the activiation page opens every single time I connect to the internet. The local store was less than helpful. one person (who seems less than delighted to work with the public) suggested I erase my history and cookies to resolve the problem..... the fact that I would lose all of my store log ins, etc, and have to re establish my home computer and re enter all my personal information with my bank, and every single company I do regular business with does not seem to be a problem for him.... His response to me indicated he thought this was somehow my fault.. certainly not comcast. Why should I have to be inconvenienced and re enter all my online payment info etc.? I am extremely annoyed....any ideas....

Loss of service 8 days ago
I have a dilemma with Comcast Xfinity high speed internet service. We experienced a heavy storm on the afternoon of Thursday May 12 and subsequently lost service. Many customers in our neighborhood were also without service so I placed a service call. At approximately 745pm while at dinner I received a text message saying that service had been restored. When we arrived home I found that we still did not have service so I placed another call and was told that they would send a tech out on Sunday May 15th. Within 5 min of arriving I was told that we needed a new modem since his equipment showed a strong signal at the entry box. I immediately went and purchased a new modem only to find that upon trying to register it online Comcast was unable to make it work and suggested that I must have gotten a bad modem. I went and purchased a second modem and tried again to add it to my account but again they were unable to communicate so they set up a third appointment for Tuesday May 17. Once again the service tech demonstrated a good signal at the entrance but could not get the modem to be recognized. He suggested we add one of their rental modems (at a cost of $10 additional per month) just to see if it would work and then we could immediately terminate the rental if so and go back to a user supplied modem. I agreed and he got one from the truck and hooked it up. It worked, so I am off to the store to purchase yet a third modem. Of course when I return it is the same story, no service. The tech had another call to make and had to leave. Later that evening I went to a different merchant and purchased yet a 4th modem of a different brand ($200+) with Xfinity printed all over the box. Calling Comcast to setup that modem gave no better results so another service appointment was set up for Wednesday with a senior tech. This tech could not explain or rectify the situation either but since having internet is mandatory for work we had no choice after 6 days but to subscribe to a rental modem for an additional $10 per month in addition to the $79.95 already paid for Xfinity Blast service. After spending $500+ on four of the top brand modems no one can explain why we can ONLY have internet service through an Xfinity rental modem. We eliminated all wireless and still could not connect directly from a modem to a laptop(s). Needless to say we are desperate for assistance.

Arris tg86 High Signal Level
Hello, I'm currently having an issue (with what I believe to be a high signal level) for the TG86. I moved into a different room in my house taking the modem with me. I tried to use a splitter to connect into my modem and my tv box. The tv box works fine but the modem will have all 4 lights on. But Windows will report it has a connection for 1 second and then it will report that there is no connection to the internet. I plugged in the coaxal cable directly from the wall into the modem for a week and it worked fine, but for the past two days I've had packet loss (1 in 3 packets will be lost) so I went outside to play with a splitter and after taking it apart and putting it back together my internet was fine. Putting the original splitter back on still causes a problem with the modem. I went to home depot and bought a new splitter and it still doesn't work. I tried to look at the logs for the modem and I believe the new splitter is giving the modem a signal level of 53 which is very high. What can I do in a situation like this?

Comcast Tech Support Please Read - Newly Introduced Firmware Bug
Hello,
The past few weeks I've had the most maddening internet issues. One minute I'm getting 125/25 and the next moment it takes 2-3 attempts to get websites to load and streaming videos freeze. Usually the issue is worse during peak times (6-9pm and Sundays). After doing some troubleshooting (and Googling) it's clear that there's a bug in the firmware (SB_KOMODO-1.0.6.16-SCM00-NOSH) being pushed to Motorola/Arris 6121/6141 modems.
I cannot imagine a non-technical person trying to explain or understand this issue to a CSR. It's going to frustrate customers and consume CSRs with calls. Please halt pushing out this firmware and work with Arris to correct. I would even suggest a roleback if that's possible. I also would guess that there's knock on effects where core switches and routers are being hit with way more requests than normal from modems looking for a connection.
Chicago Area if that helps...

Constant 1-minute outages every 20 minutes
I've noticed connection issues since about 4pm this afternoon, and didn't start recording for a pattern until evening. The last outage was a few minutes ago (5:16:35am-5:18:10am), which I waited for before posting this. The last time I experienced something like this was a couple weeks ago when an outage in my area was listed on my account page, but no outages have been mentioned all day today. When my connection is up, speed has no noticeable drop. When my connection drops, every light on my modem goes out except for power, then slowly they all come back up. The following times are rounded:
Outage - 1 minute (up at 10:18pm)
Uptime - 19 minutes
Outage - 1 minute (up at 10:38
Uptime - 19 minutes
Outage - 1 minute (up at 10:58)
Uptime - 19 minutes
Outage - 1 minute (up at 11:18)
Missed 11:38; away from computer
down at 11:57
Outage - 1 minute (up at 11:58)
Uptime - 19 minutes
Outage - 1 minute (up at 12:18)
Missed so many
down at 4:17
Outage - 1 minute (up at 4:18am)
Uptime - 19 minutes
Outage - 1 minute (up at 4:38)
Tested restarting router as advised by Comcast's troubleshoot page at 4:41, pattern continues regardless
Uptime - 19 minutes
Outage - 1 minute (up at 4:58)
Uptime - 19 minutes
Outage - 1 minute (up at 5:18)
If the pattern holds, my connection will go down 4 minutes after I send this.
[Edit]: As expected. I watch it go down at 5:36:35, then come back up at 5:38:10. I suspect that the seconds are accurate for the previous observations, but I've only measured that specifically twice.

Internet is so slow
Does anyone have any suggestions as to why the xfinity internet is so slow? It doesn't matter the time of day or how many devices I have logged in. I telecommute and this is costing me because I have to switch to my phone's data plan to upload files.
I switched from fios because they kept changing my plan and sending me new bills every week. Comcast customer service is great but I can't work with internet this slow.
Does anyone have any suggestions of settings I can check? I've rebooted everything and my account should be unlimited. I've only had it a few days and it seems to get slower by the day.

Cannot connect to Comcast Internet using ASUS RT-AC66U router behind ARRIS surfboard SB6183
If I connect my laptop directly to my ARRIS cable modem, I am able to connect to the Internet. If I try to go through my ASUS router -- wired or wireless -- I cannot.
I've tried resetting the cable modem to the factory defaults (holding the reset button for 10 seconds), power cycling the modem (leaving it off for 5 minutes before turning it back on), the router, etc. The Cat6 cables are good. Help?!?!?!
